The The following examples below illustrate exemplary ones and preferred formulations of the concentrate composition of the invention. It should be clear that these examples are for illustration only are shown and other useful Formulations falling within the scope of this invention and the claims can be easily made by the expert and of the scope and spirit not deviate from the invention.

Within this description and in the accompanying claims, Unless otherwise indicated, the weight percentages of all ingredients as a percentage by weight of the active component of the respective constituent to understand.

Examples

The following examples illustrate the formulation and performance of various compositions of the invention as well as certain particular preferred embodiments of the Er making.

exemplary Formulations containing certain preferred embodiments of the compositions according to the invention illustrate and described in more detail in Table 1 below Generally, they became according to the following Protocol formulated. The percentages by weight are referred to as "delivered" weights of said Component specified.

In a suitably sized vessel, a metered amount of water was provided, after which the ingredients were added in no particular or uniform sequence, indicating that the order of addition of the ingredients was not critical. All of the ingredients were added at room temperature and any residual water was then added. Certain of the nonionic surfactants, if present as gels at room temperature, were first preheated to make them pourable liquids prior to addition and mixing. Mixing of ingredients was achieved by using a mechanical stirrer with a small diameter blade at the end of its spin shaft. Mixing, which generally took 5 to 120 minutes, continued until the particular exemplary formulation appeared homogeneous. The exemplary compositions were readily pourable and they retained well-mixed properties (ie, stable mixtures) on standing for extended periods of time. The compositions of the example formulations are listed in Table 1. Certain comparative examples are also described in Table 1, these are given as "C" followed by an integer.

As was sufficient, all formulations of Table 1 was sufficient deionized water in a "sufficient Amount "to Deploy of 100 parts by weight of a particular formulation.

The identity of the ingredients used to prepare various formulations described herein are disclosed in Table 2 below, including the percentage of "active ingredients" where one ingredient did not have 100% "active ingredients" by weight.

cleaning efficiency

Certain of the above compositions were diluted with water at a ratio by weight of composition: water of 1:64. These diluted compositions were then subjected to the protocol of ASTM D-4488-89 Annex A5 for particulate soil which evaluated the effectiveness of the cleaning composition on vinyl tile samples. The soil applied was a particulate soil sample containing natural humus, paraffin oil, used motor oil, Portland cement, silica, lampblack, iron oxide, exchanged black clay, stearic acid and oleic acid prepared according to the protocol. Each of the soiled test vinyl tile samples was placed in the apparatus and the center of each tile with a sample of a test formulation wetted with 20 milliliters and allowed to stand for 1 minute. After about 30 seconds, another 50 milliliter sample was spotted onto a sponge (wetted with water, then wrung out to remove excess water) on a Gardener Grinding Test Apparatus. Thereafter, the apparatus was rotated 2, 4, 6, 8 and 10 times to provide 4, 8, 12, 16 and 20 sponges over the area of each of the vinyl test tiles. The reflectance values of the cleaned samples after 2, 4, 6, 8, and 10 rotations were evaluated using a Minolta Chromameter CF-110 with data processor DP-100, which evaluated the spectrophotometric properties of the sample. These readings are given in Table 3 below.

Comparative Example "C3" was one commercially available Cleaning and disinfecting composition, LYSOL Disinfectant Cleaner, "Country Scent "(from Reckitt & Colman Inc., Wayne, NJ) diluted in the manner described above and was tested. The composition C3 was used as a reference point for the cleaning performance used.

In Referring to the results given in Table 3, there is a value from "100" a white (unpolluted) Background and a value of "0" a black one Background. As can be seen from the results of Table 3, provided the composition of the invention excellent results ready or was with those of the trade available Cleaning products equivalent. Surprisingly, like from the results of C1 and especially regarding C2 at Comparison of the results for Example 1 and Example 2 can be seen, the compositions of the invention especially after 2, 4 and 6 turns of the test an unexpected excellent cleaning ready. This is unexpected and puts one close to synergistic effect.

antimicrobial effectiveness

Example 3 ^® 2000 Laboratory Automation evaluated using the Biomek workstation together with the Bio Works operating system (available from Beckman Coulter Inc., Fullerton, CA) for antimicrobial activity. The organism tested was Staphylococcus aureus at a concentration of 9 log. The Biomek mimics a microbial reduction suspension test. A portion of the organism suspension (Staphylococcus aureus) is added to 9 parts of Example 3 in a suitable container. Deionized water (DI-H ₂ O) was used as a control. The organism and the sample are then thoroughly mixed for a period of 15 seconds. Ten-fold serial dilutions are carried out in a neutralization broth. The diluted samples are then incubated at 35-37 ° C for a period of 24-48 hours. Subsequently, the surviving organisms are quantified and the log reduction as a measure of the organism survivors is calculated as follows: Log reduction = (log survivor / DI H 2 O-control) - (log survivor / sample)

According to this Test Example 3 showed a log reduction of 4.2.

As can be seen from the above results, despite the low solids contents of the compositions of the present invention, the compositions of the invention provide excellent cleaning benefits for hard surfaces, including hard surfaces with difficult to remove stains. These benefits are further complemented by the excellent antimicrobial efficacy of these compositions against known bacteria commonly found in the bathroom, kitchen and elsewhere, and such advantages clearly demonstrate their superior properties of the compositions, the cleaning and antimicrobial benefits that accompany their use, which was previously not found in the art.
